Abstract
In order to study the seismic responses and the fail modes of high-rise precast cassette structures, a shake table test was conducted on a fifteen-storey cassette structure with 55. 5 m height and 1/8 scale. Twenty-one time-history records in six levels were used in the test and the overall performance, accelerate response, displacement response were studied. The results showed that the novel precast high-rise cassette performed well in the test. Its deformation curve was a shear type, and the failure concentrated in the upper middle of the structure eventually due to the flaw of the cast-in-place process. Most of the failure concentrated in the inter-layer beams, without affecting the main structure secure. Even under a huge seismic record, the structure can still maintain its structural integrity, showing good energy dissipation capacity and good structural safety.
